'''IRNSS-1D''' is a satellite in the [[Indian Regional Navigational Satellite System|Indian Regional Navigational Satellite System (IRNSS)]] constellation. The satellite is the fourth of seven in the constellation, launched after [[IRNSS-1A]], [[IRNSS-1B]] and [[IRNSS-1C]]. The satellite is the only satellite in the constellation slated to provide navigational services to the region. The satellite will be placed in [[geosynchronous orbit]].<ref name="skyrocket">{{cite web|url=http://space.skyrocket.de/doc_sdat/irnss.htm|title=IRNSS |publisher=space.skyrocket.de |access-date=6 December 2014}}</ref> It was launched successfully on 28 March 2015 onboard ISRO's [[Polar Satellite Launch Vehicle|PSLV-C27]] from [[Satish Dhawan Space Centre]], [[Sriharikota]].<ref>{{cite web|url=http://www.ndtv.com/india-news/indias-fourth-navigational-satellite-irnss-1d-launched-from-sriharikota-750364|title=India's Fourth Navigational Satellite IRNSS-1D Launched From Sriharikota}}</ref><ref>{{cite web|title=ISRO puts India's Navigation satellite IRNSS 1B into orbit|url=http://news.biharprabha.com/2014/04/isro-puts-second-irnss-navigation-satellite-into-orbit/|work=IANS|publisher=news.biharprabha.com|access-date=4 April 2014}}</ref><ref>{{cite news|title=IRNSS 1-D launch put off|url=http://www.thehindu.com/news/cities/bangalore/irnss1d-launch-put-off/article6959479.ece|work=India|date=4 March 2015 |publisher=thehindu.com|access-date=4 March 2015}}</ref>

==Satellite==
The satellite will help in augmenting the satellite based navigation system of India which is currently under development. The navigational system so developed will be a regional one targeted towards South Asia. The satellite will provide navigation, tracking and mapping services.<ref name="irnss1b_itv">{{cite news | url=http://www.indiatvnews.com/news/india/isro-after-gslv-launch-pslv-c-with-irnss-b-likely-in-march--32118.html | title=ISRO: After GSLV launch, PSLV C24 with IRNSS-1B likely in March | work=India | date=5 January 2014 | access-date=6 January 2014 | archive-date=6 January 2014 | archive-url=https://web.archive.org/web/20140106193940/http://www.indiatvnews.com/news/india/isro-after-gslv-launch-pslv-c-with-irnss-b-likely-in-march--32118.html | url-status=dead }}</ref>

IRNSS-1D satellite has two payloads: a navigation payload and CDMA ranging payload in addition with a laser retro-reflector. The payload generates navigation signals at L5 and S-band. The design of the payload makes the IRNSS system inter-operable and compatible with [[Global Positioning System|Global Positioning System (GPS)]] and Galileo.<ref name="skyrocket" /> The satellite is powered by two solar arrays, which generate power up to 1,660 watts, and has a life-time of ten years.

===Cost===
The total cost of the mission was estimated at {{INR}}14 billion.<ref>{{cite news|url=http://www.thehindu.com/sci-tech/science/countdown-to-irnss-1d-on-march-7/article6949915.ece|title=Countdown to IRNSS 1D on March 7|author=Dennis S.
